LIQUID-HEATER.

SPECIFICATION forming part of Letters Patent No. 434,225, dated August12, 1890.

Application iiled September 25, 1889. Serial No. 825,068. (No model.)

To all whom t may concern:

Be it known that I, CHARLES YOUNG, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a new and useful Improvement in Liquid-Heaters, of which thefollowing is a specification.

My invention relates to the class of devices which heat liquids byimmersion therein, and it is intended particularly for heating the waterof bath tubs, tanks, and drinkingtroughs for animals, and for preventingthe freezing of milk in cans by heating a reservoir of water withinwhich the cans are placed.

'Ihe nature of my invention and the specific construction of the deviceswhich I employ for accomplishing the objects sought will be clearlyunderstood from the following description, reference being had to theaccompanying drawings, in which- Figure l is a central vertical sectionof my heater; Fig. 2, a detached view in elevation of the outerwick-tube of the burner and its attachments; Fig. 3, top view of theburner, showing the lame-defiector with the device upon it by means ofwhich the wick is raised and lowered through the medium of a key; andFig. 4, a View in elevation of the key employed for this purpose.

The particular burner employed, aside from certain attachments to it,which will be hereinafter described, forms no part of my invention, andit is not necessary that this burner (by which term is included not onlythe raising and lowering device for the wick, but also the auxiliaryfeeding-wick) should be employed; but other Argand burners partaking,preferably, of the nature of the ordinary student-lamp burner maybesubstituted without in any way affecting the features which constitutemy invention.

In the drawings, A is an air-reservoir, which may be of any desiredform, though I usually makevit rectangular.

tis a vertical air-tube extending upward from the air-reservoir A to aheight sufficient to bring its upper end above the surface of the liquidwithin which the heater is immersed.

C is an oil-reservoir Xed within the interior of the air-reservoir A andprovided with a vertical oil-feed pipe s extending to about the sameheight as the air-feed pipe t.

Within the tube s is a level-indicator com-y though the shape is notmaterial, so long as.

an air-space of adequate capacity is-formed ,y

about its exterior.

From the base of the air-reservoir A the wick-tube p ext-ends verticallyup through and above the oil-reservoir C, and ois a tubu lar passageconnecting the air-space surrounding the oil-reservoir C with the baseof.

the Wick-tu be p.

Surrounding the tube p is the Haine-wick n, secured to the screw-collarm, which turns freely upon the threads of the tube 1o in the usual way,and to this collar m the sleeve l is connected by means of the lug loupon the screw-collar m, which lug enters the slot c' in the sleeve Z,whereby the turning of the sleeve raises and lowers the flame-wick. Thefeed- Wick h is securely fastened at its upper end to the sleeve Z andfeeds by capillary attraction through the slots g therein. As beforestated, these features of the burner alone form no part of my invention,and they are only described in detail here in order that other featuresabout to be described may be the more readily understood. The sleeve Zextends above the top of the air-reservoir A and is provided upon itsupper end with strips f-three or four in number-supporting theflame-deiector D of refractory material. Upon the upper side of thellame-deflector and firmly secured to it are the two cross-wires eforpermitting the height of the flame-wick to be regulated.

E is a metal chimney screwed to a flange d upon the top of theair-reservoir.

Particularly when the device is employed for open-air service. it isdesirable to shield the flame from the wind, and forthis purpose a hoodF is employed, which fits over the top of the chimney, as shown. Thishood comprises the crown c, supported upon the IOO double-walled collarZ) bystrips f. The collar b is extended into a conical perforateddiaphragm a, which enters the top of the chimney E, and the base of thecollar consists of the oblique annular perforated plate a.

G is the key employed to operate the raising and lowering devicebyinsertion through the top of the chimney, and it consists of a metalrod having a suitable handle and provided upon its lower end with prongse to engage the cross-wires c. Flanges u are provided upon the lowerside edges ot' the airreservoir to be inserted in grooves on a weightedbase, if necessary, to prevent the device from floating.

In operation the lamp is lighted, the chimney E being removed for thispurpose, and the deviceimmersed in the liquid to be heated to a depthwhich will leave the upperends of the chimney E and feeding-tubes t ands above the surface. The height of the flame is regulated, whennecessary or desirable, by means of the key G, inserted through the topof the chimney, as before described, and the del'iector, spreading theflame toward the surface of the chimney, causes an intense heat, whichis rapidly imparted to the surrounding liquid. The hood F, while itpermits a ready exit of the products of combustion and unconsumed air,prevents the wind from blowing down the chimney and rain from enteringit, the crown c serving as a water-shed, and air-currents striking thechimney being delieeted upward through the pertorations in the base ainto and through the interior of the collar b and out through the spaceabove. Should any current ot air be directed downward upon the internaldiaphragm a, itis deflected upward by thefornrof the diaphragm and itseffect rendered insignilieant. Obviously all external connections whichvwould be below the surface of the liquid to be heated when the device isin operation should be made perfectly water-tight.

That I Vclaim as new, and desire to secure by Letters Patent, is-

1. In an apparatus for heating liquids by immersion therein, thecombination of the air-reservoir A, provided with the su pply-tube t,the oil-reservoir C, inclosed within the air-reservoir A, and providedwith an Argand burner and having the air-duct o, connecting thesurrounding air-space with the interior of the burner, and a metallicchimney E, surmonnting the air-reservoir A and inclosing the upperportion of the burner, substantially as described.

2.

8. In an apparatus for heating liquids by immersion therein, thecombination, with the air-reservoir A, having the air-duct t extendingupward therefrom, oil-reservoir C, inclosed within the air-reservoir andprovided with a threaded wick-tube@ having a screw-collar fm thereon, ofthe tlame-delector D, connected with the screw-collar m and providedwith the cross-wires e, a metallic chimney surmonnting the air-reservoirand inelosing the top of the burner, and air-passages connecting theair-reservoir directly with the chimney and also with the base of thewick-tube, substantially as described.
